题目描述
In mathematical terms, the sequence Fn of Fibonacci numbers is defined by the recurrence relation
F1=1; F2=1; Fn=Fn−1+Fn−2 (n>2). DZY loves Fibonacci numbers very much. Today DZY gives you an array consisting of n integers: a1,a2,...,an . Moreover, there are m queries, each query has one of the two types:
- Format of the query " 1 l r ". In reply to the query, you need to add Fi−l+1 to each element ai , where l<=i<=r .
- Format of the query " 2 l r ". In reply to the query you should output the value of modulo 1000000009 (109+9) .
Help DZY reply to all the queries.
输入格式
The first line of the input contains two integers n and m ( 1<=n,m<=300000 ). The second line contains n integers a1,a2,...,an (1<=ai<=109) — initial array a .
Then, m lines follow. A single line describes a single query in the format given in the statement. It is guaranteed that for each query inequality 1<=l<=r<=n holds.
输出格式
For each query of the second type, print the value of the sum on a single line.
输入输出样例
输入#1
4 4 1 2 3 4 1 1 4 2 1 4 1 2 4 2 1 3
输出#1
17 12
说明/提示
After the first query, a=[2,3,5,7] .
For the second query, sum=2+3+5+7=17 .
After the third query, a=[2,4,6,9] .
For the fourth query, sum=2+4+6=12 .
